Drawing Circuit Diagrams
Use straight lines and correct symbols
Ensure clarity and neatness
Example: Series circuit with bulb and switch
Student Task – Draw This Circuit
Draw a circuit with a cell, bulb, and switch
Extension: Add a buzzer and resistor
What is current?
Current is the flow of electric charge
If there is charged particles (such as electrons) moving from one area to another, then there is a current.
Current flows from:
Positive Negative
Flow of current
Notations and equations:
I = Current
Q = Charge
t = time
Each electron has a negative charge
Current is how many of those charges are passed along per second
I = Q/t
Current is the charge per second
The units for current is Amperes (A)
The units for charge is Colombes (C)
